Abstract

PCT No. PCT/EP90/00050 Sec. 371 Date Sep. 18, 1990 Sec. 102(e) Date Sep. 18, 1990 PCT Filed Jan. 10, 1990 PCT Pub. No. WO90/08738 PCT Pub. Date Aug. 9, 1990.The present invention relates to a process for preparing basic aluminum compounds having the general formula (1) [Al2 (OH)x Cly (SO4)z]n (1) where: n is at least equal to 1 x=2-4.0 y=2.0-3.40 z=0-0.30 and x+y+z=6 by means of a reaction of alumina with hydrochloric acid, possibly mixed with sulfuric acid. The alumina is caused to react in alumina/acid(s) stoichiometric conditions to obtain the compounds of formula (1). The reaction is carried out by milling alumina in liquid phase under heavy stirring.
